Articles having a hardness equivalent to 9 or more on the Mohs scale
Hard ceramic wares for laboratory or technical use (Mohs 9+)
HSN 6909 12 00 (ceramic wares for laboratory, chemical, or other technical uses with a hardness equivalent to 9 or more on the Mohs scale) is not covered by a Bureau of Indian Standards Quality Control Order and carries no Partner Government Agency clearance requirement at the tariff-line level. Import follows the standard customs procedure: Importer-Exporter Code, bill of entry, commercial invoice, packing list. Ceramic wares of lower hardness, or those intended for agricultural or packaging use, may fall under sibling tariff lines within Chapter 69 that carry distinct compliance obligations.
The absence of compliance at this tariff line is specific to hard technical-grade ceramic wares meeting the Mohs 9 threshold; ceramic articles classified by end use — laboratory versus agricultural versus conveyance and packing — sit at different 8-digit positions within heading 6909, and mis-stating intended use on the bill of entry can trigger re-classification on examination. Customs re-classification carries retrospective duty recovery and potential detention pending the applicable licence or standard. Confirm hardness grade and functional category against the customs tariff before import.
